DESCRIPTION OF EMBODIMENTS

FIGS. 1A through 1C illustrate an operation process of a handheld electronic device according to an embodiment of the present invention.

Referring to FIG. 1A, the handheld electronic device 100 of the present embodiment is in a retracting state, wherein the upper body 110 and the lower body 120 are stacked with each other, and the upper body 110 is located immediately on a carrying surface 120 a of the lower body 120. In general, the upper body 110 is provided with a display screen 180 for displaying image or text information, the lower body 120 is provided with a keyboard 190 for a user to input information, while the present embodiment is not limited thereto. Along with the continuous development of the functions of the handheld electronic device 100, the display screen may be a touch screen by which a user can input information in a touch manner, and therefore the user may perform an operation between the upper body 110 and the lower body 120 back and forth when using the handheld electronic device 100. In other embodiments, both of the upper body 110 and the lower body 120 may be provided with their display screens to accomplish a dual-screen display or operation in a touch manner.

Then, referring to FIG. 1B, the upper body 110 slides relative to the lower body 120, such that a first end 112 of the upper body 110 slides from a position immediately on the lower body 120 to a position outside a first side 122 of the carrying surface 120 a, and then when the upper body 110 reaches a predetermined position. At this time, the upper body 110 exposes the keyboard 190 or other devices on the carrying surface 120 a of the lower body 120.

Next, referring to FIG. 1C, after reaching the predetermined position, the upper body 110 rotates relative to the lower body 120, and a second end 114 of the upper body 110 enters a recess 124 on the carrying surface 120 a of the lower body 120. Thereby, the handheld electronic device 100 becomes a spreading state, and an included angle θ is formed between the carrying surface 120 a of the lower body 120 and a top surface 110 a of the upper body 110, wherein the included angle θ is larger or equal to 90 degree and smaller than 180 degree.

FIG. 2 is an explosive view of the handheld electronic device of FIGS. 1A through 1C. Referring to FIG. 2, accompanying with the requirement of forming the recess 124 on the lower body 120, the structural design of the lower body 120 is considered in the embodiment. For example, an inclined plane S is formed on the shell of the lower body 120, such that the upper body 110 can lean against the inclined plane S after rotating relative to the lower body 120, to restrict the degree of rotation of the upper body 110.

A sliding mechanism 130 is disposed between the upper body 110 and the lower body 120 for driving the upper body 110 sliding relative to the lower body 120. The sliding mechanism 130 of the present embodiment includes a first sliding member 132 and a second sliding member 134, which are configured to slide relative to each other, and the first sliding member 132 is connected to the upper body 110. In addition, to accomplish the rotation of the upper body 110 relative to the lower body 120 after the upper body 110 reaches the predetermined position, a pivot axle 140 is disposed between the lower body 120 and the sliding mechanism 130. The pivot axle 140 is connected between the second sliding member 134 of the sliding mechanism 130 and the lower body 120, and therefore the sliding mechanism 130 along with the upper body 110 can rotate relative to the lower body 120 via the pivot axle 140.

Specifically, the pivot axle 140 is disposed between the recess 124 and the first side 122, while the axial direction of the pivot axle 140 extends along the first side 122 of the carrying surface 120 a. Herein, the pivot axle 140 can refer to any rotating mechanism for providing pivot function, for example, a bearing and a seat disposed between the second sliding member 134 and the lower body 120, or other equivalent members.

FIGS. 3A through 3C respectively show both of a side view and a cross-sectional view of the handheld electronic device 100 from the retracting state to the spreading state as illustrated in FIGS. 1A through 1C. Referring to FIGS. 1A through 1C, 2, and 3A through 3C, when the handheld electronic device 100 is transformed from the retracting state as shown in FIGS. 1A and 3A to the spreading state as shown in FIGS. 1C and 3C, the first end 112 of the upper body 110 slides from the position immediately on the lower body 120 to the position outside the first side 122 of the carrying surface 120 a by the sliding mechanism. In addition, after reaching the predetermined position, the upper body 110 rotates relative to the lower body 120 by the pivot axle 140, and the second end 114 of the upper body 110 enters the recess 124 on the carrying surface 120 a of the lower body 120 so as to form the included angle θ and leans against the inclined plane S.

In the present embodiment, when the handheld electronic device 100 n the spreading state, the second end 114 of the upper body 110 enters the recess 124 on the carrying surface 120 a of the lower body 120, and therefore the unity of profile of the handheld electronic device 100 can be improved. In addition, since the upper body 110 and the lower body 120 forms the included angle θ in the spreading state, the viewing angle of the user in watching the display screen 180 of the upper body 110 is adapted to the gesture in operating the keyboard 190 of the lower body 120. Therefore, it is comfortable to watch the image or text information on the display screen and inputting information via the keyboard 190 as well.

Furthermore, in the present embodiment, the carrying surface 120 a of the lower body 120 and the top surface 110 a of the upper body 110 together form a step-free continuous surface. Said step-free design is suitable for operating back and forth between the upper body 110 and the lower body 120. For example, when the display screen 180 of the upper body 110 is a touch screen, the user can input information in the touch manner and perform operations back and forth between the display screen 180 of the upper body 110 and the keyboard 190 of the lower body 120. The said step-free design eliminates the height difference between the upper body 110 and the lower body 120 in operating the handheld electronic device 100, and thus the smoothness and feel in operating the handheld electronic device 100 are enhanced.

In another embodiment, the upper body 110 and the lower body 120 may have smooth profiles, and therefore a gap or a height difference exists between the upper body 110 and the lower body 120 in the spreading state. However, the second end 114 of the upper body 100 still enters the recess 124.

In further another embodiment, the upper body 110 and the lower body 120 are both provided with their display screens, wherein the carrying surface 120 a of the lower body 120 and the top surface 110 a of the upper body 110 together form a step-free continuous surface, so as to accomplish a seamless display of dual screen or a touch operation on the two display screens.

Referring to FIG. 2, a first elastic member 152 is disposed between the first sliding member 132 and the second sliding member 134 to provide an elastic force driving the first sliding member 132 sliding relative to the second sliding member 134. Specifically, the first elastic member 152 can be a semi-auto spring, such as a coil spring, a helical spring or other elastic member capable of driving the first sliding member 132 and the second sliding member 134 to accomplish the semi-auto sliding, so as to provide the elastic force required in the process of retracting or spreading the upper body 110 and the lower body 120. In other words, the active device array substrate 100 is capable of performing a semi-auto sliding operation. When the upper body 110 is on the retracting position as shown in FIGS. 1A and 3A, the user only needs to push the upper body 110 from the retracting position to the right side in the figures for a little stroke, and then the upper body 110 can automatically slide to the predetermined position as shown in FIGS. 1B and 3B.

Moreover, referring to FIG. 2, a second elastic member 154 is provided between the second sliding member 134 and the lower body 120 to provide an elastic force driving the upper body 110 rotating relative to the lower body 120. In the present embodiment, the second elastic member 154 may be a torsion spring disposed on the pivot axle 140 and connected the second sliding member 134 and the lower body 120. However, the pivot axle 140 can further be a torsion axle itself. Whereby, the second elastic member 154 is no more required, and the pivot axle 140 can apply a torque on the second sliding member 134. Furthermore, even if the handheld electronic device 100 is not provided with the second sliding member 154 or the pivot axle 140 is not a torsion axle, the upper body 110 can still be raised manually to form the spreading state.

No matter the handheld electronic device 100 is in the retracting state or the spreading state or in the transforming process between the two state, the second elastic member 154 applies a unidirectional torque on the second sliding member 134, such that the second sliding member 134 drives the whole sliding mechanism 130 and the upper body to rotate relative to the lower body 120 by the unidirectional torque and forms the spreading state in FIGS. 1C and 3C.

Reversely, as the handheld electronic device 100 is transformed from the spreading state to the retracting state, the upper body 110 is pressed toward the lower body 120, i.e. applying a force on the first end 112 of the upper body 110 to counteract the torque of the second elastic member 154, to drive the upper body back to the predetermined position as shown in FIGS. 1B and 3B.

Then, the user only needs to push the upper body 110 from the predetermined position to the left side in the figures for a little stroke, and then the upper body 110 can be automatically drawn back to the retracting position as shown in FIGS. 1A and 3A by the elastic force of the first elastic member 152.

In another embodiment, the second elastic member 154 can further be a helical spring disposed between the second sliding member 134 and the lower body 120, or the second elastic member 154 can be other equivalent members to provide the unidirectional torque on the whole sliding mechanism 130 and the upper body 110.

In addition, considering that the recess 124 of the lower body 120 may be exposed as retracting or spreading the handheld electronic device 100 and affect the appearance of the handheld electronic device 100, a shielding member for shielding the recess 124 can be provided on the position corresponding to the recess 124.

Specifically, with respect to the handheld electronic device 100 of FIG. 2, the inclined plane S is formed on the shell of the lower body 120, and the recess 124 is exposed at two opposite sides 126 a and 126 b adjacent to the first side 122. Accordingly, a U-shaped ring 160 is disposed at the first side 122 of the carrying surface 120 a, and two arms 162 of the U-shaped ring 160 extends to the two opposite sides 126 a and 126 b to cover the recess 124.

In this embodiment, the U-shaped ring 160 leans against the upper body 110 and the two arms 162 of the U-shaped ring 160 is connected to the pivot axle 140. Therefore, when the upper body 110 rotates relative to the lower body 120, the U-shaped ring 160 is driven to rotate relative to the lower body 120 at the same time, and the two arms 162 of the U-shaped ring 160 can shield the recess 124 exposed at the two opposite sides of the lower body 120 in the process of retracting or spreading the handheld electronic device 100.

FIG. 4 is a side view showing a handheld electronic device in the spreading state according to another embodiment of the present invention. The main difference between the present embodiment and the previous embodiment is that the profile of the U-shaped ring 260 of the present embodiment should be amended, such that the two arms 262 of the U-shaped ring 260 rotate and protrude outside a bottom surface of the lower body 220 as the handheld electronic device 100 is becoming the spreading state, for being as standing legs. The inclined angle of the handheld electronic device 200 standing on a plane can be controlled by adjusting the length of the standing legs.

FIGS. 5A through 5C show a handheld electronic device transforming from a retracting state to the spreading state according to further another embodiment of the present invention. The difference between this embodiment and the previous embodiment is that the U-shaped ring 360 and the lower body 320 of the present embodiment are formed integrally. In other words, the U-shaped ring 360 is fabricated with the shell of the lower body 320 and fixed on the lower body 320. Thereby, the recess 324 is hided in the U-shaped ring 360 without being exposed. Furthermore, to permit the second end 314 of the upper body 310 entering the recess 324 of the lower body 320 in the spreading state, dimensions of the relative members should be considered, wherein the width A of the U-shaped ring 360 is greater than the width B of the upper body 310, such that after the upper body 310 rotates relative to the lower body 320, a second end 314 of the upper body 310 can enter the recess 324 of the lower body 320.

FIG. 5C omits the upper body 310 of the handheld electronic device 300 for clearly illustrating the sliding mechanism 330 and the pivot axle 340. Referring to FIGS. 5B and 5C, since the U-shaped ring 360 is integrally formed with the shell of the lower body 320, further another movable U-shaped ring 370 can be provided and disposed in the recess 324 surrounded by the U-shaped ring 360. The configuration and operation of the U-shaped ring 370 are similar to the U-shaped ring 160 of the previous embodiment. Therefore, when the handheld electronic device 300 is transformed into the spreading state, the U-shaped ring 370 can shield the recess 324 and the sliding mechanism 330 and the pivot axle 340 in the recess 324, which are exposed during the rotation of the upper body 310.

FIGS. 6A through 6C are respectively cross-sectional views showing a handheld electronic device transforming from a retracting state to the spreading state according to further another embodiment of the present invention. The main difference between the present embodiment and the previous embodiment is that the present embodiment omits the U-shaped ring and instead modifying the profile of the upper body 410 and the lower body 420 of the handheld electronic device 400, wherein an end of the lower body 420 corresponding to the recess 424 is shrunk in its thickness to form a step portion 426 exposing the recess 424, the sliding mechanism 230 and the pivot axle 440. The upper body 410 has a bump portion 416 corresponding to and having a profile complying with the step portion 426, such that the bump portion 416 and the step portion 426 closely meet and cover the recess 424 when the handheld electronic device is in the retracting state.

FIG. 7A is a diagram showing a handheld electronic device in a spreading state according to another embodiment of the present invention. FIG. 7B is an assembly view of the upper body and the lower body of the handheld electronic device of FIG. 7A. Referring to FIGS. 7A and 7B, the recess 524 formed on the carrying surface 520 a of the lower body 520 has a profile complying with the second end 514 of the upper body 510, and the recess 524 is formed integrally with the lower body 520. By which, the unity of profile of the handheld electronic device 500 in the spreading state can be improved, and the region of the carrying surface 520 a adjacent to the recess 524 is maintained planar. Therefore, not only the drawback caused by the height difference between the upper body 510 and the lower body 520 in operating the handheld electronic device 500 can be eliminated to enhance the smoothness and feel in operating the handheld electronic device 500, but also the seamless display of dual screen or the touch operation on the two display screens can be accomplished.

Furthermore, to permit the second end 514 of the upper body 510 entering the recess 524 of the lower body 520 in the spreading state, the recess 524 of the present embodiment extends to two opposite sides of the carrying surface 520 a, and two corners of the second end 514 of the upper body 510 are rounded, such that the second end 514 of the upper body 510 can enter the recess 524 of the lower body 520 after the upper body 510 rotates relative to the lower body 520. More specifically, the recess 524 can be covered by the second end 514 of the upper body 510 and hidden under the upper body 510.

In summary, the handheld electronic device accomplishes the relative motion between the upper body and the lower body by adopting a sliding mechanism and a pivot axle to form an included angle after spreading the upper body relative to the lower body, and a portion of the upper body adjacent to the lower body enters a recess of the lower body after rotating the upper body relative to the lower to form a step-free continuous surface. Therefore, the unity of profile of the handheld electronic device can be improved. The comfort and the convenience in using the handheld electronic device can be increased, and the smoothness and feel in operating between the upper body and the lower body can be enhanced. In addition, the appearance and the feel of operation of the handheld electronic device can further be improved by disposing a U-shaped ring on the lower body for shielding the recess, modifying the profile or dimensions of the upper body and the lower body, or varying the fabricating manner or the profile of the recess. Furthermore, a seamless display of dual screen or a touch operation on two display screens can also be accomplished in the present application.
